SPECIFICATION forming part of Letters Patent No, 387,978, dated August14, 1888,

Application filed March 24, 1%88.

To all 1071-0771, it may concern:

Be it known that I, EDWIN RUTHvnN LAN- DON, a citizen of the UnitedStates, and a resident of Chicago, county of (look, and State ofIlllllOlS,lllVt,lll vented new and useful Improve. ments in MetalDoor-Mats; and I do hereby declare the following to be a full, clear,and exact description of my said invention.

My invention relates to that class of metal mats in which the mesh isformed of crimped or sinuous strips of sheet metal arranged side by sideon their edges, and is designed to secure a maximum of scraping-surfacewith the least possible weight of metal, to construct a mat which shallpresent no sharp ends, and to provide for simplicity of manufacture.

In the accompanying drawings, which are made a part of thisspecification, Figure 1 shows a view of my improved mat; and Fig. 2showsa modi fied form of construction in which the frame is limited tothe sides, the ends of the mat being left exposed. Fig. 3 shows atransverse sectional View of the mesh.

My invention consists in constructing the mesh of the single strip ofsheet metal, A, of suitable width,crimped to form V-shaped corrugationsof uniform size, the said strip being repeatedly doubled upon itself,the apexes of the several corrugations of adjacent folds being broughtincontact,so that a mesh is formed which is uniform or regular throughoutthe extent of the mat, and in the use, if desired, of a flexibleframework in mats of this class. The mesh is held together by the rods0, which may be either still or flexible, and which pass through holespunched in the successive folds of the strip A at c, equidistant fromthe edges Serial No 168,341. (No model.)

of said strip, and are made fast in or to the outer frame, B, which mayconsist of a flexible wire or of one-halfioval metal of the same widthas the strip A, as shown in the drawings, and which may pass completelyaround the mat, as in Fig. l, or only along the sides thereof, as inFig. 2. If the irame B passes completely around the mat, additionalstrength is secured by the use of clips D,firmly attached to the frame Bat the ends of the mat and projecting inwardly, and being of sufficientlength to allow the rods 0 nearest the ends of the mat to pass throughholes in said clips made for that purpose. The straight metal strip E,preferably of the same metal as the strip A, passes through the entirelength of the mesh and has holes at e to accommodate the rods C, and isintroduced for the purpose of preventing the ends of the mat from beingpulled out or elongated by any accident which might tend to so damageitby straightening the strip A. Instead of the single strip E,two ormore such strips may be used. Neither do I limit the use of thetransverse rods. 0 to the number shown in the drawings; but more or lessmay be used, as desired.

What I claim as new, and desire to protect by Letters Patent, is-

A strip of erimped metal doubled upon itself, so as to form the mesh ofa mnt,in combination with retaining rods, frame, and the strengtheningbar is, substantially as described herein.
